original code slightly modified and compressed:c.width*=1 p=(m,n)=>(8+C(8*m))*(1-((n+6)/12)**3)**0.5 for(j=-6;j<6;j+=0.1)for(i=0;i<6.28;i+=0.05)x.fillRect(960+540*((j+6)*C(j-t*9)/14+S(i)*p(i,j))/(14-C(i)*p(i,j)),540-540*j/(14-C(i)*p(i,j)),3,3)

u/lewdev

We can all see the compressed code when using beta.dwitter.net so you don't have to show it in your title.
u/fentbiggesthater

when you uncompress the code its actually different than the code in the title.
u/zachygreen

i should have clarified but the code in the title was the original code i made. i had to change p to a variable instead of a function but i wanted to preserve the old code. also i do know about beta dwitter
u/AmoreFS

awesome i love you all
